AMD Instinct MI300 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The AMD Instinct MI300 and NVIDIA GeForce RTX 5070 Mobile occupy opposite ends of the GPU spectrum, one a 600 W datacenter accelerator with 128 GB of HBM3, the other a 50 W mobile part with 8 GB of GDDR7. The database contains no direct head-to-head benchmark results for these two products, and the MI300 has no recorded benchmark scores or nearest rivals. The RTX 5070 Mobile, however, carries a full set of nine benchmark entries and four nearest-rival comparisons. This analysis therefore relies on the recorded data for the RTX 5070 Mobile, the architectural specifications for both, and the percentile placements to draw comparisons.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for the AMD Instinct MI300 versus the NVIDIA GeForce RTX 5070 Mobile. The MI300 has an average benchmark score of zero and an empty benchmark array, meaning no recorded tests populate its profile. The RTX 5070 Mobile, by contrast, has an average benchmark score of 29,928 across its nine recorded tests. Its percentile versus all GPUs stands at 75, placing it above the majority of tracked graphics hardware. The MI300 sits at the 50th percentile, but with no average score to anchor that figure, the percentile alone carries limited interpretive weight.

Within the RTX 5070 Mobile’s own benchmark suite, the strongest results appear in compute-oriented tests. Geekbench OpenCL returns a score of 122,238, while Geekbench Vulkan reaches 116,960. Passmark G3D records 20,355, which is the highest of the Passmark group. Passmark GPU Compute follows at 8,279. The lower Passmark scores, such as DirectX 10 at 129, DirectX 11 at 192, DirectX 12 at 93, and DirectX 9 at 214, reflect the mobile part’s modest graphics throughput in legacy API workloads. Passmark G2D, a 2D graphics test, produces 896.

The nearest rivals for the RTX 5070 Mobile provide context. The NVIDIA GeForce RTX 3070 Ti holds an average score of 29,945, which is 0.1 percent higher than the RTX 5070 Mobile’s 29,928. The NVIDIA GeForce RTX 2080 Ti averages 29,783, putting the RTX 5070 Mobile 0.5 percent ahead. The AMD Radeon RX 6800 scores 30,095, placing the RTX 5070 Mobile 0.6 percent behind, and the AMD Radeon RX 6700 scores 30,433, making the RTX 5070 Mobile 1.7 percent slower. These deltas are narrow, all within roughly two percentage points, indicating that the RTX 5070 Mobile performs in the same band as those desktop-class GPUs from previous generations.

Because the MI300 has no benchmark data, the head-to-head comparison cannot be expressed in scores or deltas. The RTX 5070 Mobile’s recorded performance, however, demonstrates that it competes closely with the RTX 3070 Ti and RTX 2080 Ti, while trailing the RX 6800 and RX 6700 by small margins. The MI300’s zero-score profile means no similar numeric comparison exists.

Architecture Differences

The two GPUs share a 5 nm process node and TSMC as the foundry, but nearly every other architectural element diverges. The MI300 uses the Aqua Vanjaram chip with CDNA 3.0 architecture, while the RTX 5070 Mobile uses the GB206 chip with Blackwell 2.0 architecture. The MI300 belongs to the Instinct (MIx) generation, and the RTX 5070 Mobile belongs to the GeForce 50 Mobile generation.

Transistor counts differ by an order of magnitude. The MI300 packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The RTX 5070 Mobile contains 21,900 million transistors on a 181 mm² die, with a density of 121.0 million per square millimeter. The MI300’s die is roughly 5.6 times larger in area and holds about seven times more transistors.

Memory configurations are equally distinct. The MI300 offers 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RTX 5070 Mobile provides 8 GB of GDDR7 on a 128-bit bus, with 384.0 GB/s of bandwidth. The MI300’s memory bandwidth exceeds the RTX 5070 Mobile’s by a factor of roughly 13.8. The RTX 5070 Mobile’s memory clock runs at 1500 MHz with 24 Gbps effective, while the MI300’s memory clock is 1300 MHz with 5.2 Gbps effective, though the massive bus width compensates.

Compute resources show a similar gap. The MI300 has 14,080 shading units, 880 texture mapping units, and zero ROPs. Its pixel rate is 0 MPixel/s, and its texture rate is 1,496.0 GTexel/s. FP32 performance reaches 47.87 TFLOPS, with FP16 at 47.87 TFLOPS (1:1). The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. Its pixel rate is 68.40 GPixel/s, and its texture rate is 205.2 GTexel/s. FP32 performance is 13.13 TFLOPS, with FP16 also at 13.13 TFLOPS (1:1). The MI300’s FP32 throughput is about 3.6 times higher, though the RTX 5070 Mobile offers ROPs and pixel output that the MI300 lacks entirely.

The RTX 5070 Mobile includes dedicated ray tracing cores, 36 of them, and tensor cores, 144 of them. The MI300 lists no RT cores and no tensor cores in the database. Clock speeds also differ: the MI300 has a base clock of 1000 MHz and a boost of 1700 MHz, while the RTX 5070 Mobile has a base of 907 MHz and a boost of 1425 MHz. The MI300’s higher boost clock aligns with its larger power envelope.

Power and physical specifications reinforce the divide. The MI300 has a TDP of 600 W, uses two 8-pin power connectors, and requires a suggested PSU of 1000 W. It measures 267 mm in length and 111 mm in height. The RTX 5070 Mobile has a TDP of 50 W, uses no power connectors, and is classified as an integrated graphics processor (IGP) with no dimensions recorded. The MI300 has no display outputs, while the RTX 5070 Mobile’s outputs are listed as portable device dependent. API support also differs: the MI300 has N/A entries for DirectX, OpenGL, and Vulkan, while the RTX 5070 Mobile supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The MI300 wins on raw compute scale. Its FP32 output of 47.87 TFLOPS more than triples the RTX 5070 Mobile’s 13.13 TFLOPS. Texture rate follows the same pattern, with the MI300 at 1,496.0 GTexel/s versus 205.2 GTexel/s. Memory bandwidth is the largest differentiator, 5.32 TB/s versus 384.0 GB/s, a gap that favors workloads with massive data movement. The 128 GB capacity versus 8 GB also tilts toward large-model or high-resolution datasets. The MI300’s 14,080 shading units and 880 TMUs provide the parallel execution width for compute-heavy tasks.

The RTX 5070 Mobile wins on graphics pipeline completeness. It has 48 ROPs and a pixel rate of 68.40 GPixel/s, while the MI300 has zero ROPs and a pixel rate of 0 MPixel/s. The RTX 5070 Mobile also includes 36 RT cores and 144 tensor cores, features absent from the MI300’s profile. API support gives the RTX 5070 Mobile another advantage, with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 all present, versus N/A entries for the MI300. The RTX 5070 Mobile’s 50 W TDP and IGP form factor make it suitable for portable systems, whereas the MI300 requires a 1000 W PSU and occupies a 267 mm card length.

The RTX 5070 Mobile’s benchmark results reinforce its positioning. Its Geekbench OpenCL score of 122,238 and Vulkan score of 116,960 show strong compute and graphics API performance for a mobile part. Its Passmark G3D score of 20,355 and GPU Compute score of 8,279 indicate balanced general-purpose and graphics throughput. The nearest rival comparisons, with deltas under two percent against desktop GPUs like the RTX 3070 Ti and RTX 2080 Ti, show that the mobile part holds its own against older high-end desktop hardware.

The Verdict

The data indicates two different purposes. The AMD Instinct MI300 is a compute accelerator with no display outputs, no graphics APIs, and no ROPs. Its strengths, 153,000 million transistors, 128 GB of HBM3, 5.32 TB/s bandwidth, and 47.87 TFLOPS FP32, point to server-side workloads where graphics output is irrelevant. The RTX 5070 Mobile, with 36 RT cores, 144 tensor cores, full DirectX 12 Ultimate support, and a 50 W TDP, targets portable gaming and workstation systems. Its benchmark scores, averaging 29,928, place it at the 75th percentile of all GPUs, with nearest rivals within 1.7 percent in either direction.

For users selecting based on recorded performance, the RTX 5070 Mobile has the only benchmark data available. The MI300 has no scores, no rivals, and a 50th percentile that cannot be verified against a numeric average. The RTX 5070 Mobile’s performance profile is clear: it sits between the RTX 3070 Ti and RTX 2080 Ti, slightly behind the RX 6800 and RX 6700, and delivers strong OpenCL and Vulkan results. The MI300’s role is inferable from specifications alone, and those specifications describe a device built for throughput, not display.

The verdict splits cleanly. The MI300 suits compute environments that need memory capacity and bandwidth, with its 128 GB HBM3 and 8192-bit bus. The RTX 5070 Mobile suits graphics and portable use, with its ROPs, RT cores, tensor cores, and API support. Neither product can substitute for the other. The database shows no overlap in benchmark results, and the architectural gaps, particularly in ROPs, memory type, and power draw, make the choice straightforward based on workload.
